Mechanical interactions of subducting oceanic plates with the overriding accretionary wedges
Tkáčiková, Tatiana ; Žák, Jiří (advisor) ; Kusbach, Vladimír (referee)
Analog models have been widely used as a tool to reconstruct and understand the geological process, too great to observe in real-time. Subduction of solid mass seamounts, the significant topographic elevations, was focus of several studies by analogue "sandbox" and numerical modeling of recent years. However, the natural seamounts are commonly surrounded by loose blocks as a part of the Ocean Plate Stratigraphy. This thesis focuses on the topography of the ocean basin, analog modeling of seamount subduction and the effect of the topographic elevations on the deformation of the accretionary prism, during subduction of the various shapes of seamounts. A series of experiments were performed to study these processes and specially, the effect of the loose blocks on the structure of the wedge stratigraphy, particularly, on formation of mélanges.
